When I want to show people what an intro is and tell them a bit about the demoscene, I usually show them the intro Elevated, which won the PC 4k compo at Breakpoint 2009. For me it really shows the talent of Iq and the other people who created it. It’s truly amazing what can be done in just 4 kilobyte!
